Commercial Skills Test Information Management System (CSTIMS)

The Commercial Skills Test Information Management System (CSTIMS) is an internet-based tool that provides jurisdictions and third-party examiners a consistent way to track the scheduling and entry of test results for commercial driving skills tests.

CSTIMS enforces jurisdiction-defined rules to manage commercial drivers license (CDL) skills testing. CSTIMS alerts authorized users when business rules have been violated and provides reports to detect patterns of potential fraud.

CSTIMS offers the following web services to help jurisdictions optimize their experience with the application:

  • Legacy CDL Service: This service allows a jurisdiction to retrieve test results for their applicants from CSTIMS using either a DLN or a date range.
  • Legacy CSTIMS Tablet Web Service: This service is used by a state that uses tablets for administering the skills test. It allows the tablet to retrieve existing skills test schedules from CSTIMS and to submit the test scores to CSTIMS to avoid manual entry.
  • CSTIMS Applicant Search Service (CASS): This service allows CSTIMS to query for applicant data from the specific state‚Äôs host system. When the applicant is found and retrieved, the data then pre-populates the applicant record in CSTIMS, thereby providing data integrity and greatly reducing human error.
  • Test Results Service 2.0 (TRS 2.0): This RESTful service is a combination and upgrade of the Legacy CDL Service and the Legacy CSTIMS Tablet Web Service which includes the ELDT status and the testing model for the Modernized Skills Testing model.

Please read the CSTIMS Privacy Policy before using CSTIMS. Also, before using the application, you must take and successfully complete the CSTIMS Privacy Awareness Training course.
